The FI forum would probably be best for this question. (even though it is a tuning question...)
Very conservative timing would be 10-11 degrees. Lower boost levels get away with 15 degrees, maybe more. Depends on if you're intercooled or not too.
A/F - conservative - 11:1, you can go up from there, maybe as much as 11.5:1. Depends on if you're dyno tuning or street tuning too.

tuning Depends on boost and Comp. ratio your running. a stock motor say 8 or 9 psi start at 9* and work you way up to say 11 or so watching it closely. AFR from 11-11.8. If possible do it on a mustang dyno do a pull through all your gears and make sure intake air temps dont raise to high.
